Signal Conditioner monitors and protects machinery.
April 17, 2009 -
Utilizing DSP technology, Sentry G3 Turbine Supervisory System features 4 channels that can be independently programmed to provide continuous monitoring and protection across broad spectrum of measurement regimes, including vibration, expansion, temperature, and speed. Integral color LCD display and drive facility provide immediate viewing and access to machines parameters. Each transducer signal is buffered and available via front panel analog connection arrangement.

More Features, More Flexibility with Sentry G3
Condition monitoring specialists SENSONICS have introduced the Sentry G3 machinery protection monitor, a high performance signal conditioning unit. The new G3 monitor builds upon the established range of Sentry protection systems developed by Sensonics and is designed to be the most flexible and feature rich Turbine Supervisory System available. It provides a universal platform for the interfacing of various sensor types in compliance with the API 670 standard.
Each of the units four channels can be independently programmed to provide continuous monitoring and protection across a broad spectrum of measurement regimes, including vibration, expansion, temperature and speed. Sentry G3 utilises the latest DSP technology, so once a channel is set up and running, the resulting alarm relay and analogue output facilities are independent from the remaining module functionality, ensuring a scalable, high integrity configuration.
The unit has an integral intuitive colour LCD display and drive facility which provides immediate viewing and access to the machines parameters. Several modes of display are available to suit specific applications, such as an alarm historian and parameter trending per channel. It also provides the necessary power source for the selected transducer, providing for 2 (ICP type) or 3 wire accelerometer variants, ± 24V proximity probe systems, LVDT's and a range of speed and temperature sensors. Each transducer signal is buffered and available via the front panel analogue connection arrangement while a USB interface is provided for programming the unit and for storage of channel history and settings.
The G3 system offers excellent channel density with up to 24 measurement channels in a 3U format, also each channel can provide independent analogue outputs of current and voltage for DCS connection, in addition to an alarm relay. Further alarm relay expansion is possible through connection to digital outputs at the rear of the module.
The system is designed for mounting in a custom 19" rack assembly which also contains a dual redundant power supply option.
Sentry G3 provides state-of-the-art protection for the following modes:
Measurement - Absolute bearing and relative shaft vibration, displacement and thrust position, speed, phase and reverse rotation, differential and casing expansion, rod drop and temperature.
Turbine Specialist Measurement - Shaft eccentricity, mark - space differential expansion, rotor to stator air gap.
Flexible Configuration - LPF, HPF, tracking and notch filters, programmable warning and danger alarms, cross channel voting, FTT, harmonic and phase analysis, programmable transducer supply, scaleable module hardware with plug-in DSP card, up to 4 channels,
Dual redundant power supply, gateway communications module, USB programmable, alarm defeat and module park and calibration modes.
